Phys. Rev. D 35, 3530–3532 (1987)Phase transition in a nucleon-antinucleon systemReceived 30 January 1987; published in the issue dated 1 June 1987 We have examined the phase structure of a nucleon-antinucleon plasma in Walecka’s relativistic mean-field approximation originally due to Theis et al. who have shown that the nuclear-matter system exhibits a phase transition at Tc≃200 MeV for zero baryon density. It is found that the inclusion of a small nonvanishing chemical potential which, in turn, implies a nonzero baryon density does not negate this result. © 1987 The American Physical Society URL:
